Bio:Nearing death due to overexposure from solar radiation, Superman--his physical and mental capabilities having been enhanced due to his solar overcharge--scanned his genetic code with his microscopic vision and copied the 8 billion letter sequence into a book, along with instructions on how to combine human and Kryptonian strands of DNA. Providing these to scientist Leo Quintum--who had long struggled to produce a viable clone of Superman, only succeeding in creating damaged Bizarro replicas--along with genetic samples from both himself and Lois Lane, Quintum would be able to grow the child in the wake of the original Superman's apparent passing. In time, the boy would grow to become the new Superman, eventually working alongside his father and descendants in the Superman Squad.
